Aerosol protection system

Abstract

Hygiene regulations and social distancing are very effective in blocking short distance infections. During the lockdown, the distance rules can usually be adhered to, but what happens when the actual lockdown is over and the people meet again in a confined space? Then additional effective and efficient protection is essential to stabilize infection rates. Since the viruses are spread by contact and droplet infection, technical devices are required that effectively intervene in the chain of infection and effectively block infection. An effective protection is the respiratory mask as known since 100 years.An alternative to mask is an aerosol protection system for various applications in environment. The protection system consists of adjustable air sucking device and air blowing device in different form factors based on application. The aerosol protection system uses either an air curtain or air shield to prevent the aerosol going from one side of the curtain or shield to the other side.

The invention claimed is: 
     
       1. An aerosol protection system to block passage of an aerosol from each side of the aerosol protection system to the other side comprising:
 A plurality of guiding horns having a trapezoidal shape with a narrow end comprising an opening and a wide end comprising a second opening; 
 an air blowing device located at the top of the aerosol protection system comprising a first guiding horn, of the plurality of guiding horns, having an air outlet at the narrow end and an air inlet and a plurality of adjacent blowing fans on the wide end of the trapezoid; 
 an air sucking device located at the bottom of the aerosol protection system comprising a second guiding horn, of the plurality of guiding horns, adjacent to a square prism, the second guiding horn comprising an air inlet at the narrow end and an air outlet at the wide end adjacent to the square prism and the square prism comprises a plurality of adjacent sucking fans adjacent to the wide end of the guiding horn, a replaceable air filter adjacent to the fans, and a removable mesh filter holder configured to hold the air filter inside the air sucking device; 
 
       a holder to hold said air blowing device and said air sucking device; 
       the air blowing device operates at a first vertical surface or plane and said air sucking device operates at a second vertical surface or plane with a distance between them to provide an air blowing curtain and an air sucking curtain; the air blowing device and the air sucking device comprises a means to adjust an orientation and a direction of the air blowing curtain or the air sucking curtain by configuring an air flow angle; 
       the performance of said aerosol protection system is adjusted by bending or rotating inward or outward of said air blowing device or said air sucking device and changing the distance between the first vertical surface or plane and said second vertical surface or plane. 
     
     
       2. The aerosol protection system of  claim 1 , wherein said air blowing device uses said first guiding horn to control a speed, a cubic feet per minute (UM), and said orientation or said direction of a blown air. 
     
     
       3. The aerosol protection system of  claim 2 , wherein said air sucking device uses said second guiding horn to control an air sucking power and said orientation or said direction of a sucked air. 
     
     
       4. The aerosol protection system of  claim 3 , wherein said contaminated air sucked by said air sucking device is filtered before being released to the environment and said replaceable filter is a HEPA (high efficiency particulate air) filter or a ULPA (ultra-low particulate air) filter that is replaceable after a period of use. 
     
     
       5. The aerosol protection system of  claim 3 , wherein said CFM and said air sucking power are adjusted by changing a DC (direct current) or an AC (alternating current) operating voltage used by said plurality of adjacent blowing fans and said plurality of adjacent sucking fans. 
     
     
       6. The aerosol protection system of  claim 5 , wherein said blowing assembly and said sucking assembly use three or more adjacent fans. 
     
     
       7. A method for providing aerosol protection, the method comprising:
 A plurality of guiding horns having a trapezoidal shape with a narrow end comprising an opening and a wide end comprising a second opening; 
 an air blowing device located at the top of the aerosol protection system corn rising a first guiding horn, of the plurality of guiding horns, having an air outlet at the narrow end and an air inlet and a plurality of adjacent blowing fans on the wide end of the trapezoid; 
 an air sucking device located at the bottom of the aerosol protection system comprising a second guiding horn, of the plurality of guiding horns, adjacent to a square prism, the second guiding horn comprising an air inlet at the narrow end and an air outlet at the wide end adjacent to the square prism and the square prism comprises a plurality of adjacent sucking fans adjacent to the wide end of the guiding horn, a replaceable air filter adjacent to the fans, and a removable mesh filter holder configured to hold the air filter inside the air sucking device; 
 
       an aerosol protection system that uses a holder to: hold the air blowing device connected at the top of said holder; and hold the air sucking device connected at the bottom of said holder; to blow air from top of said holder in a first vertical surface or plane by the air blowing device to create a first air curtain to block passage of an aerosol from one side to the other side of said first air curtain; and 
       suck said aerosol by said air sucking device at the bottom of said holder in a second vertical surface or plane to create an air sucking curtain that has an adjustable distance from said first vertical surface or plane. 
     
     
       8. The method of  claim 7 , wherein a speed, an orientation and a direction of the air flow is achieved by the first or second guiding horn. 
     
     
       9. The method of  claim 7 , further the speed of the air blowing device, and an air sucking power of the air sucking device are controlled by changing a DC (direct current) operating voltage or an AC (alternating current) operating voltage of the plurality of adjacent blowing fans and the plurality of adjacent sucking fans.
